Willllllllm UNITED, STATES PATENT XVILLAM EDVARD VVINBY AND WILLIAM MARSTON YVINBY, OF BIRMING- HAM, COUNTY OF VARWIOK, ENGLAND.

oABLE-'RAMwAY PULLEY.

SPECIFICATION forming part of Letters Patent N 0. 425,282, dated April 8, 1890. Application led November Z5, 1889. Serial No. 331,532. (No model.) Patented in England August 18, 1887. No. 11,277.

T all whom, zit may concern:

Be it known that We, VILLIAM EDWARD WINBY and WILLIAM MAusToN WINBY, subjects of the Queen ot Great Britain, and residents of Birmingham, in the county ot lVa-rwick, England, have invented certain new useful Improvements in Gable Tramways, (for which we have obtained a patent in Great Britain, No. 11,277, dated August 1S, 1887,) of

fo which the following is a full, clear, and exact specification thereof.

This invention relates to certain new and useful improvements in cable tramways, and it has for its object to provide an improved i 5 pulley for carrying the cable round the curved parts of cable-tramway lines.

The novelty resides in the peculiar combinationsand the construction, arrangement, and adaptation of parts, all as more fully here- 2o inafter described, shown in the drawings, and then particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the let- 2 5 ters ot' reference marked thereon, form a part ot this` specification, and in which- Figure 1 is a vertical section illustrating our invention. Fig. 2 is a side view, partly in horizontal section.

3o Like letters ot' reference indicate like parts in bot-h views.

Referring now to the details of the drawings by letter, A designates the bell-pulley, made of cast-steel and having the sectional 3 5 lligure represented. The said pulley is turned perfectly true on the outside or bearing part for the cable to work upon, and is provided with anA internal stalk or spindle A', with a central point or bearing at the bottoni in the socket a, bolted or riveted to the iron baseplate B on the girder B. The upper end of this socket 0, is shaped to'forin an oil cup or chamber l). Vithin this socket is a bearing or bushing c for the shoulder d of the stalk A of the capstan.

D is the cable, supported on the annulailedge D2 o't the bell-pulley. The top of the pulley is provided With oil-feeding holes e, through which oil is fed to the oil cup or 5o chamber in the socket. One end of the baseplate B passes under ka lug f on the girder E and the other end is secured to the girder B by means of a bolt and clamp, as at f. F is a man-hole over the said bolt, and it has such a diameter as to admit of the hell-pulley passing through it for examination and repairs. To effect the removal, the bolt f is released, when the pulley can be drawn backward under the said man-hole, the end of the baseplate coming out from under the lug on the 6o girder.

G is the tube, supported as shown, and a pillar is bolted to the girder at g to support the side piece H ot the cable-tube.

The bell shape of the pulley, arranged as 6 5 shown, keeps the dirt and water from the bearing and forms a very simple and efficient means for carrying the cable around the curved parts.

That we claim as new is 7o 1. The combination, with the socket, ot' the bell-shaped pulley having an internal stalk stepped in said socket, substantially asdescribed.

2. i The combination, with the socket formed 7 5 with an oil-chamber at its upper end, of the bell-shaped pulley having ,an internal stalk stepped in said socket an d provided at its top with oil-feeding holes, substantially as shown and described. 8o

3. The combination, with the socketformed with an oil-chamber at its upper end, of a bushing insaid socket and the bell-shaped pulley stepped iu said socket, and provided at its upper end with oil-feeding holes, and with a shoulder bearing on the top of said bushing, substantially as described.

1. The combination, with the girder having a lug, as shown, of the base-plate held at one end beneath said lug, the pulley carried by 9o said base-plate, and a removable fastening for the other end of said base-plate beneath the man-hole, substantially as shown and described.

In testimony that we claim the foregoing We have hereunto set our hands this 11th day ofApril, 1889.
